For our project, we wanted to see if it was possible to create a semi truck with an electric engine. Our team,

Ecovision, consisted of Aja, Damen, Daphne and Darci. This is to show you what we did, and how we did it.

OPENING

Think about a design for your car and decide whether to use

aluminum or wood as the car body.

STEP ONE

Pick a piece of wood & lightly

mark where you’re going to cut it.

STEP TWO

Using the radial arm saw, cut out along the line on the wood. Make

sure to turn on the dust collector

before using the saw, and wear

safety goggles.

STEP THREE

Grab a piece of scrap metal and mark four pieces that you will later cut out to use for

axel holders.

STEP FOUR

Using the band saw, cut out the four pieces of metal. Before using it, turn on the dust

collector and wear safety goggles.

STEP FIVE

Using the center punch, punch each

piece twice, one close to the top,

the other close to the bottom. You want them to be even, so measure

before hand.

STEP SIX

Grip the pieces one by one into the vice grip.

With the electric drill, make holes

where the center punch

marks are. Repeat for all of

the pieces.

STEP SEVEN

Keep the pieces gripped in, using the hammer, bend them to get a 90 degree angle.

STEP EIGHT

Collect four screws from the screw

boxes, they should be pretty small.

STEP NINE

Using a screwdriver,

attach the little metal pieces to the wood car

body. Make sure to mark where you’re going to put them first,

you want them to be even.

STEP TEN

Using a hack saw, cut out two copper rod pieces about 5

inches across.

STEP ELEVEN

Get a pack of four wheels. Either big or

small will work.

STEP TWELVE

Hammer one wheel onto one side of

the rod. Insert the rod into the back 2 axel holders. Once

you have that, hammer on the

other wheel.

STEP THIRTEEN

Put the motor together using the

instructions.

STEP FOURTEEN

Using the rod coming with the

motor, repeat step thirteen for the

front.

STEP FIFTEEN

Solder the battery pack wires to the motor. And you’re done! (with the

car at least)

STEP SIXTEEN

SOLID WORKS

After testing, we concluded that it would be possible to make a semi truck with an electric engine. It probably

wouldn’t be as efficient as a diesel semi truck, but it would work. Also, we learned our car could hold about 80 grams

of weight at the most.
